Overview
The PCM1789PWRG4, produced by Texas Instruments, is a high-performance, single-chip, 24-bit, stereo audio digital-to-analog converter (DAC). This device employs an enhanced multi-level delta-sigma (ΔΣ) modulator and supports sampling rates from 8 kHz to 192 kHz. It is designed for high-quality audio applications, offering differential voltage outputs and an integrated analog low-pass filter. The PCM1789PWRG4 is available in a 24-pin TSSOP package and operates over a temperature range of –40°C to 85°C.
